What would Native Advertisers like to see?

I have this app that pulls your market information and see's what ads are currently running in that space and finds patterns on why it is working (based on my years of native advertising experience and some principals I have developed.)

It then creates an ad set for you to go test and you can set this to run automatically so you get new tests following different patterns it see as the market changes.

Question: Do you think there are any other feature's advertisers would like to see in this platform?
